プレリリース：Undertale

This page details pre-release information and/or media for Undertale.

Starmen.netでの公開

2013年2月4日、Toby氏はフォーラムサイト『Starmen.net』上のフレンドのフォーラムにて、ジョークを含めた返信を投稿。その投稿で彼は、ゲーム『MOTHER』の非公式改造バージョン『UnderBound』の続編である『UnderBound 2』を開発中だと明かした（当時『UnderBound』は存在しないため、おそらく冗談）。その投稿に表示されていた画像・音楽は、実際にUndertaleの初期段階のものであり、最終段階でのバージョンとは複数異なる箇所が存在する。

右に表示されている画像は、公開されたものの中で最も古いUndertaleのスクリーンショット。見た目は完成版とほぼ同じではあるものの、画面下の選択肢が異なる。この段階では "ACT"（こうどう）が "TALK"（はなす）に、"MERCY"（みのがす）が "SPARE"（にがす）になっており、完成版では存在しない "SPELL"（まほう）が存在し（グラフィック自体は残っているものの、使用はされていない）、LV表示もまだ存在しない。フロギーは "TestMonster"（テストモンスター）と呼ばれており、胸部分の見た目が異なる。

当時のフリスクは枠線の色が黒であり、髪と靴には現在のものより暗い色が使用されていたようだ。完成版では、これらは明茶色に変更されている。

Pre-release	Final

Compared to the final, the early version has blockier graphics. LV is next to the player's name, and there is an extra stat EN, which Toby says stands for English, though more likely stands for Energy, which is a unused stat in the demo's code.

Pre-release	Final

Dated April 5th, 2013 (one month before the demo release), this leaf puzzle was made a bit easier in the final version. Other parts of the ruins were also lacking markings or cracks on the ground at this point.

Happy Toriel with no horns. The original Boss Monster design lacked horns, but they were added because Toby felt it made them look too much like mimigas from Cave Story (a noted inspiration).

Mettaton Essay

On Toby Fox's twitter, he notes that at one point, Mettaton would save your essay to the hard drive as an image, but it was buggy, and thus was removed.

Bandcamp Demo Soundtrack Differences

To do: The "Start Menu" combines four tracks into one for some reason. Split this track up and compare it to the unused "Start Menu" tracks in the demo. The final game's Bandcamp soundtrack has differences in it as well.

The demo's soundtrack on Bandcamp features a few musical differences compared to the demo.

Fallen Down

Bandcamp	Demo

This track is used when you first meet Toriel. The Bandcamp version is a slowed down, lower-pitched version of the demo's version in the files, which in turn is slowed down, and lower-pitched ingame.

Hotel Battle Music Prerelease Name

The song on the OST Can You Really Call This A Hotel, I Didn't Receive A Mint On My Pillow Or Anything was named Hey This Wasn't Really What I Was Expecting From a Hotel, For Example You Didn't Even Leave a Mint on My Pillow when revealed in a Kickstarter update, and has the filename hey_this_wasnt_really_what_i_was_expecting_from_a_hotel_for_example_you_didnt_leave_a_mint_on_my_pillow.mp3 on Toby Fox's website. It was made on October 30th, 2014, at 8:58 AM.

Stronger Monsters WIP

This prototype version of Stronger Monsters is found on Toby's website, as well as in a Kickstarter update. The only major difference seems to be that the end is shorter. It was made on December 18th, 2014, at 8:16 AM.

Compare the end of this track with the final:

Unreleased Music

Various unreleased music tracks were posted to the Undertale Tumblr on the day before the game's 1-year anniversary.

Early Alphys

A calmer, less quirky-sounding version of Alphys's theme. It was rewritten for the final version because Toby felt it was too similar to "a certain lab song from another game".

Early Spear of Justice

An early version of Undyne's battle theme. Although the melody is mostly the same, it has a considerably more melancholy and less aggressive tone compared to the final version due to being written before Toby "really knew Undyne’s personality".

Early Undertale

An early take on the eponymous song. Compared to the final version, this is less bittersweet-sounding and is played in a minor key. Toby was inspired to change the guitar backing to a new melody (which itself served as the basis for Memory and His Theme) after "hearing a certain song".

Dog Hole

Definitely meant to be an area theme, but it doesn't sound quite like anything else on the soundtrack. Maybe that's why it was scrapped...?

"Dogtroid"

Dogsong arranged as a parody of the Metroid ending theme. Apparently, if you completed the game quickly enough, you would have gotten an image of the Annoying Dog in a bikini as a "reward":

Concept Art

Papyrus

Concept art for what appears to be an early version of Papyrus (based on the pose). According to Toby, the gray pixels are a result of resizing in Microsoft Paint, so this may not be what the original version actually looked like.

Grillby

Burgerpants

Concept art for Burgerpants with some... colorful commentary. According to Toby, Burgerpants is the only character whose final design matches the concept art 1:1.

Marsh

Concept art for the marsh with some some choice words for cyan-lovers. The final version of this area has cyan water anyway.

Toriel

According to Toby, this is concept art for Toriel.
